upload speed fluctuation

Hello,

i have M350 fibre broadband, which is supposed to give me 350 down and 35 upload. I am hardwired to the router via cat 6 and on a Hub4.

Is it normal for my upload to drop to as low as 10Mbps during the day. Obviously its much higher frist thing in the morning and the middle of the night, hitting closer to above advertised speeds.

Was pretty consistant for the first few months of ownership, Only really noticed this fluctiation since the free upgrade to the hub 4.

thanks

matt

Could you access your router using http://192.168.0.1/ or http://192.168.100.1 for modem mode . You shouldn't need log in, select the 'Check Router Status' option and paste your 'Downstream', 'Upstream', and 'Network Log' tabs? Please copy/paste this data as text, split between multiple posts (Sometimes you have to click 'Post' twice due to an error message).

Could you please create a BQM (Broadband Quality Monitor) here, and post the live link?

Ah sorry HUB 4. There is a bug and you must log in and access 'Advanced Settings / Tools / Network Status' to get the stats I asked for!

The current upstream stats look ok, however the timeouts, hlighlighted, are a concern.

We'll need to let the BQM run for a while to see the quality of your line.
